You can figure power dissipation using the voltage drop since they are all interrelated. If you know the voltage drop across a resistor or other device like a motor then the power dissipation can be calculated as voltage times current or if you dont know the current but do know the resistance you can square the voltage and divide by the resistance. More than one way to skin a cat.
